METAL CONTAINER.

Application filed lvarch 18, 1920. Serial No. 366,752.

/ 1o @ZZ whom, t may concern.'

Be it known that I, Lotus M. KnnonLrUs, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Metal Containers, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have content plated applying that principle, so as to distinguish it'from other inventions.

The present improvement, relating, as indicated, to a. metallic container, has more particular regard to a container of this sort that will be adapted to preserve in airtig t condition polishing` compositions which require to be removed as a solid body when desired for use. Such compositions are usually placed in the container in a plastic condition, and upon subsequently solidifying they sometimes expand slightly so that it becomes difiicult to withdraw the cake ofcomposition intact from the can.

The object of the invention, accordingly, is to provide a container or can which may be conveniently opened without breaking` or injuring the cake of material contained therein, and to the accomplishment of this object the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting', however, but one of various mechanical forms in which the principie of the invention may be used.

In said annexed drawing Fig. l is a central vertical section of my improved container; Fig. 2 is a top plan view thereof; Fig. 3 is a transverse section taken on the plane indicated by theA line 3 3, Fig. l; and Fig. l is an enlarged sectional detail.

rlhe body of the can, as best shown in Figs. l and 3, consists simply of a plain cylinder formed by rolling up a rectangular metal sheet until its edges 2 and 3 overlap to form a longitudinal seam. Solder 4 is then applied externally of the cylinder along the edge 2, so as to leave the inner overlapping edge 3 substantially entirely free. Accordingly, when the ends of the can are removed, as will be presently described, the body l may be readily separated along the line of such seam by simply inserting a sharp instrument, such as a knife or the like, between said overlapping edges 2 and 3, whereupon the line of solder d can be broken and such body sprung off or freed from the cake of material contained therein, without injuring the latter.

The two ends 5 of the container are to all intents and purposes identical, each consisting of a dished plate having a lateral fiange 6, the central depressed portion of the plate being adapted to fit snugly within the ends of such body l, while the flange 6 projects therebeyond a slight distan.e, as clearly shown in Fig. 3. On one side such fla-nge 6 is further `extended to provide a laterally projecting ear 7 that may be seized, as by a pair of pineers, pliers or familiar keys, when it is desired to remove the corresponding end from the body. To seal the ends in place a thin strip of solder S is applied in the er;- terior angle formed between the body l and such projecting flange 6, as best shown in Fig. 4. Such solder is, however, not heavy enough to interfere with the breaking away of the cover in the fashion just described.

In use, the body of the can has the one end fittedr and soldered in place, whereupon the can is filled and the other end applied and similarly soldered in place. VlVhen it is desired to remove the contents of the can, the same being in the form of a solid cake or stick as already indicated, one or both ends are removed and the body then slit along the line of the seam, whereupon such cake or stick is left entirely free and may be readily removed.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, pro vided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. A wholly removable container for slowly solidifying material comprising removable end plates, a body portion formed of a cylinder of sheet metal, of greater height than the diameter of said end plates joined to said end plates and providing an underlapped portion of substantial width, a sealing element applied to the outer edge of said cylinder along a line of the body of said cylinder' spaced from the other edge, said underlapped portion being free over the remaining area thereof, whereby Cutting the outer ply Will free the sheet material from said contents.

2. A Wholly removable container for slowly Solidifying material Comprising' countersunk end plates, a body portion formed of a cylinder' of sheet metal, of greater height than the diameter of said end plates Wrapped about the oountersunk portions of said end plates and providing` an u'nderlapped portion of Substantial Width, a sealing element applied to the vouter edge of said cylinder along a line of the body of said cylinder spaced from the other edge, said underlapped portion being free over the remainingg,l area` thereof, whereby cutting the outer ply will free the sheet material from saio Contents, the Countersunk Cover plates, l'or the respective ends of the cylinder so formed, having projecting ears in Vertical alignment so as to be each readily removable, preliminaryT to Cuttingl 'the overlapped portion of the body of the container, to Wholly remove the same from said solidified material.

Signed by me this 15th day of MarchJ 1920.

LOUIS M. KREGELUS.
